Several types of poly(methyl methacrylate)/poly(dimethyl siloxane) graft copolymers (PMMA‐ g ‐PDMS) were synthesized using macromonomer technology. Three types of PMMA‐ g ‐PDMS with different PDMS chain length were obtained. The effect of siloxane chain length on surface segregation of PMMA‐ g ‐PDMS/poly(2‐ethylhexyl acrylate‐ co ‐acrylic acid‐ co ‐vinyl acetate)[P(2EHA‐AA‐VAc)] blends was investigated. The blends of PMMA‐ g ‐PDMS with P(2EHA‐AA‐VAc) showed surface segregations of PDMS components. The surface enrichments of PDMS in the blends depended on the PDMS chain length, significantly. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 86: 1736–1740, 2002
